1. Faster processing speed: Generally, the mechanical processing speed of graphite can be 2-5 times faster than that of copper; And the discharge machining speed is 2-3 times faster than copper;

2. The material is not easily deformed: it has obvious advantages in the processing of thin rib electrodes; The softening point of copper is around 1000 degrees, which is prone to deformation due to heating; The sublimation temperature of graphite is 3650 degrees; The coefficient of thermal expansion is only 1/30 of that of copper.

3. Lightweight: The density of graphite is only 1/5 of that of copper, which can effectively reduce the burden of machine tools when using large electrodes for discharge machining; Suitable for applications on large molds.

4. Low discharge consumption; Due to the presence of C atoms in spark oil, during discharge machining, high temperatures cause the C atoms in spark oil to decompose and form a protective film on the surface of the graphite electrode, compensating for the loss of the graphite electrode.
